Device description

Wiring Duct Cover

Removable protective element for closing the open side of a wiring duct and retaining wires and cables placed inside it.

A wiring duct cover is intended to close the internal space of the duct after conductors have been installed. It helps retain wires inside the duct, protects them from accidental mechanical contact, and provides an orderly appearance for internal wiring in an electrical cabinet or distribution board.

The cover is installed on a compatible duct base using snap features, guides, or another connection provided by the design. It can be removed for installation, modification, or maintenance of the wiring.

The cover dimensions must match the width and construction of the corresponding wiring duct. Depending on the version, relevant characteristics include material, length, width, fixing method, mechanical strength, flexibility, and operating conditions.

Selection should take into account compatibility with the duct series and size, suitability for repeated removal and refitting, material, and the intended fixing method.

Components in this subcategory

This subcategory includes removable covers, snap-on covers, flexible covers, and other closing elements for internal wiring ducts used in electrical panels and cabinets.
